The Effect of Quality of Surface and Color upon the 
Absorption of Light. 

The lack of information and methods for the use of artificial 
illuminants in economic commercial illumination prompted this in- 
vestigation and study of the effect of quality of surface and color 
of wall coverings upon the absorption of light. The ultimate object 
of the investigation was to deduce a table of luminosity factors from 
the data thus obtained vzhich v;ill show the illuminating constants of 
the various colors with respect to white as a standard so that it v/ill 
be a commercial benefit to Illuminating Engineers and of general 
interest to the trades. 

The materials investigated, for obvious reasons, were con- 
fined to various kinds of wall papers ( plain, ingrain, and crepe), 
tapestry burlaps and canvas , and paints. The method of procedure 
was quite original embracing only standard sources of light with a 
diffusing plate and the V.'eber photometer, thereby reducing many 
chances of errors. As Cap. Abney says:- "A serious study of color 

must be undertaken v/ith a clear mind, a good eye, and a fair 

supply of patience" , and in this class of photometrical v/ork the re- 
liability of results depends primarily upon the personal error of 
the observer. 

A brief review of light and the quality of surface may be 
of introductory interest. IVhen a beam of light strikes any material 
substance one or more of three things must occur^. First, the 
light may be reflected, as from the surface of polished silver; second

it may be transmitted through a substance, as with a transparent body- 
like glass; third, it may be neither reflected nor transmitted, but 
absorbed, as in case of a substance like charcoal. With most 
substances these 4hree qualities are foiind at the same time; the 
first being very useful fpr economic illumination in a wall covering 
and the others detrimental. 

Many preliminary investigations of apparatus used in 
this study resulted in slight modifications of the Instruments. The 
condition of the standard source of light demands extreme attention 
in order to secure accurate results. Heretofore the Weber photom- 
eter #157, was operated on a standard of amyl-acetate whose flame 
is a source of much error. The luminous intensity of the flame 
varies greatly with the degree of purity of the surrounding air 
diminishing in proportion to the quantity of carbonic acid gas in 
the air increases. The presence of the flame, moreover, gives a 
temperature rise which adds to the fatigue of the observer and creates 
small air currents through the instrument which destroy the constancy 
of the standard flame. Then too, the movements of the observer when 
balancing the instruments for a reading will cause the flame to vary 
in luminous intensity and its height and condition are very hard to 
determine. A variation in height of one mm. will introduce an error 
of one percent. 

In order to avoid the errors thus introduced, the instru- 
ment was equipped with a miniature low voltage electric light after 
one suitable for photometrical purposes was obtainedr Small 
tantalum lamps were used for the following reasons:.

First, they have an excellent color; 

oecond, they show a remarkable constancy in candle power after 
having been thoroughly seasoned; 

Third, when operated under their rated voltage, owing to their 
positive temperature coefficient, their resistance assiomes a constant 
value, thus making possible an accurate adjustment of the terminal 
voltage and hence candle power which ^^in remain constant throughout 
a balance regardless of the conditions mentioned that effect a flame; 

Fourth, the candle power can be regulated with precision by 
varying the voltage across the lamp terminals; 

Fifth, the life of such a lamp was found by experiment to be 
long. 

Considerable time was spent in securing a suitable diffus- j 
ing plate which gave a true matt white surface. Experiment on paper? I 
surfaces coated with barivun sulphate, plaster of parls and the like 
showed that a surface of plaster of paris treated with oil stone 
powder imtil the surface was true and matt gave the best surface and 
was a very reliable diffusing standard. ' 

The illumination upon the standard diffusing plate of 
plaster of paris was secured from a thoroughly seasoned and standard- 
ized 32 candle power lamp, calibrated in the usual manner against the 
United States Bureau of Standards 16 candle power secondaries at 
their rated voltage over their terminals. 

The location of the instruments was decided for general 
convenience and is shown diagramatically in plate #1. Referring par- 
ticularly to the plate #1 wherein similar reference letters indicate 
like parts throughout the several settings; "A" is the standard of

illumination referred to above. It is rigidly attached to a movable 
arm which rotates "B" about a central point "C" and is also mounted 

so that the point "G" is rigid with respect to the experimental 
table "H". Upon the arm "B" is mo-unted an index pointer "D" which 
travels with arm "B" over the vernier "E". 

The standard diffusing plate "P" and also the surface under 
consideration when taking data are placed in the plane of the pivot 
"C" supported by the stand "G" on the table "H". The surface '*^'' 
was maintained in a fixed position throughout the investigation in 
the plane of the center of rotation "C* and normal to the sight tube 
"l" of the V/eber photometer. 

The VJeber photometer consists of a tube" 1" which is mount- I 
ed horizontally and is attached to a sleeve sliding on a stout metal I 
post screwed into the top of the containing case. The tube "1" con- 
tains a circular opal glass plate "R" which is movable by a rack and 
pinion operated by a milled head "Ulf. Attached to this member is an 
index finger which moves over an appropriate scale"T" placed on the 
outside of the tube, by means of which the photometer settings are 
accomplished. 

A lamp case slips on the larger end of the tube in which 
is placed the miniature tantalum standard lamp"S*'; the lamp being 
supported by a sleeve inserted through the ventilating duct which 
is provided for a flame standard. The other end of tube "1" carries 
a sleeve upon which is centered the tube "S" whose axis is at right 
angles to that of tube "1". The sleeve is provided with a clamping 
device "P" for holding the tube at the desired angle of inclination. 
During this work, however , the plane was that of the horizontal.

On the interior of the tube "2" at "R" is mounted a 
Lummer-Brodhun contrast prism while at the smaller end "0" is located 
the telescopic eyepiece for viewing the optical screen "F", The 
ejepiece is slotted and contains a slide which has three circular 
openings into which are placed at "M" and "N" red and green glass 
respectively with the opening at "L" left hlank for white. The 
other end of the tube is fitted with a flat and square box "J" in 
which various opal plates may be placed, and it is surmounted by a 
narrower tube "I" for the admission of the measured rays of light 
from the stahdard plane. 

The photometer was maintained in a fixed position through- 
out the work in order to avoid the possibility of some errors, the 
distance between the photometer and the screen, however , is immaterial 
so long as the screen is well within the cone of vision of the photom- 
eter. The instruments were adjusted in position after which every 
precaution was observed to secure an accurate calibration. 

The length of the arm^B" was chosen four feet from center 
of pivot to the approximate center of the standard lamp filament "A" 
for the following reasons :- 

First, this distance permitted the use of a secondary standard 
of high candle power and thus materially reduce the sources of error; 

Second, four feet provided a convenient distance for the 
physical construction of very rigid apparatus; 

Third, it provided a very convenient laboratory setting; 

Fourth, the distance it gave between the diffusing plate and 
the lamp was sufficient to reduce the effect of the uneven intensity

from the various sides of the filament to a minimum and to all purpose 
gave a uniform distribution about the center of the field of vision 
of the Weber photometer; 

Fifth, the intensity of illumination thus produced rrave a 
very good working value under nearly every color conditioK; 

Sixth, the results obtained gave an ideal case of twofoot 
candles, a standard commercial value of illumination, and at the same 
time materially simplified the calculations. 

The photometer was thoroughly cleaned and calibrated so as 
to be direct reading by establishing a scale of foot candles to corree 
pond to the distance of the balancing screen "R" from the standard. 
The calibration was based upon the lav/ of inverse squares by a manual 
setting of the screen at a given distance and balancing the instrument 
in the regular way, which is byvarying the distance "V" of the opal 
plate "R" from the standard "S" until both halves of the field of 
vision appear equally illuminated. In the investigations, however, 
the light sources ( secondary) were , in many instances, of a very dif- 
ferentcolor so that a working comparison v/as made between their red 
and green color constituents and from these comparisons a relation 
was secured for expressing the illuminating power of one light source 
in terms of the other. This relation is given in the form of the 
curve as Plate #2. 

The required tv/o observations, one in red and the other in 
green, are secured by means of the red and grien glasses in the eye- 
piece of the photometer. The intensity apparent by settings of the 
red and green are read directly from the calibration and the true 
intensity of illumination found by combining the intensity as shown

by the red with that of the green through a factor "K" in order to 

finally express the equivalent intensity of white. Expressed math- 

eciatically this statement is: "Intensity" = "R" "K" . The factor 

was secured from the makers table of the relations of "K" to the 

ratio of SIl^R^ for the quality glass used in instrument # 157, 
red 

The data and curves herewith given show the values of the 
intensity of illumination and the percentage of reflecting power of 
the various samples for every 10 degrees of rotation of the standard 
light from the position giving the incident ray normal to the surface 
under observation. 

In the data the following notation was used through out : *«- 

r = photometer balance in red. 

g = photometer balance in green. 

Ratio = green divided by red. 

E- 
K. = corresponding value of j^ from curve. 

P.O. 111. = true intensity of iilximination in foot candles . 

^um. = fo reflecting power or luminosity. 

In several cases where the percent reflecting power was com- 
paratively small, the balances were not at all sensitive so that, 
since the error of such a balance would give entirely erroneous 
results, they were rejected and such a point of sensitiveness is 
indicated by the symbol n . The data, needless to say, was 
obtained in the photometer room where all surroundings are dull black.

The unit of intensity of illiomination commonly used is 
the "foot candle" which may "be defined as the intensity produced 
upon a surface one foot from a standard flame of one candle power 
so placed that the rays strike the surface perpendicularly or 
normal to the surface. Hence in determining the intensity of 
illumination on any given surface from a light source in any 
given position there are two factors which must "be considered; 
first, the distance of the surface from the source, and second, 
the angle which the surface makes with the incident ray. Prom 
this we are able to derive the rule:- " multiply the candle- 
power intensity of light at the given angle hy the reduction 
factor for that angle and divide the product by the square of 
the distance;' 

Experiment showed that for the incident ray normal to 
the surface and constant in value and a varying angle of reflect- 
ion, the intensity of Illumination on the surface varied only 
a very small amount throughout the useful range of the pho- 
tometer. This setting with a constant incident ray also 
gave evidence that the colors have a much greater effect on the 
angle of incidence than for the angles of emission. Since in 
practical illumination both angles vary for each particular 
position, it was decided from the above named effects of color 
to maintain the angle of emission constant in securing the data 
herewith given. 

We well know that in any enclosed space the light re-

fleeted from the 'bounding surfaces may constitute a considerable 
portion of the total light, and, therefore, if the surfaces are 
colored the general illumination will be strongly colored quite 
without consideration of the illuminant. This principle will be 
recognized as analogous to the modification of the color of light 
by a shade over the source. Hence strong or dark colored walls 
will give the dominant tone to the color rather than that of 
thelight source. 

Diffiised light from reflecting surfaces is very useful 
for, by a mixture of diffused and regular reflection, the quantity 
of light which will reach a surface is determined. Of the two 
the diffused reflection is the more important. 

A study of the data and curves will show at a glance 
that the quality of the surface and color are very important 
factors relating to the absorption of light. The value of 
Plaster of Paris, a matt white s^orface, was used as the standard 
of comparison being 100 % reflecting power as compared with the 
colors. It must be remembered, however, that the absolute re- 
flecting power is only about 82jS of the total light received. 

Experiment on this surface as well as the various other 
samples proved that the so-called "lav of the cosine" is not 
true in consequence of the deviation of the law of cosine cf 
the incident ray. This conclusion was also drawn by Wright 
some years ago in elaborate experiment. 

Next to the white we see several tinted colors in the

light yellows, pulp, and pink that give a percentage reflecting 
power of important magnitude. This is no douht due to the 
strong reflection of white light from the mass of uncolored 
fibers composing "':he surface. The very light colors in general 
diffuse well owing to the uncolored component of reflected light, 
and, v/ith the exception of the yellows, the reflecting power di- 
minishes very rapidly as the tone of color "becomes deep. 

The curves show that for all smooth surfaces the re- 
flection follows very nearly the law of the cosine. A very 
noticeable feature is in the increased reflecting power with the 
roughnessof the surface. This is very apparent in the commercial 
papers known as ingrain where a great percentage of the surface 
fibers reflect white light from the uncolored portion. Roughness 
in a paper in use, however, permits the surface to become coated 
with a film of dust and thereby reduce the reflecting power. 
Contrasted with this a smooth light tinted surface will diffixse 
well at first but loses its power of reflection rapidly as it 
becomes soiled. A glance through the data will show that th? 
dark blues, greens, and browns in all their varieties have very 
low reflecting powers and in" commercial work should, therefore, 
be avoided where effective Illumination is desired. 

In fabric or burlap wall coverings there is considerable 
loss from multiple reflections from the surface of the dyed fiber 
producing an effect of "richness" of color. This too. gives a 
more uniform diffusion which is very noticeable in the regularity 
of all the curves for fabric coverings. A very interesting

feature to note in the burlaps is that coating the top surface 
of the projecting fibers with silver will add about 10/= to the 
effective reflecting power of the ground surface color. Sample 
#76, a very light burlap, is conspicuous for a large percentage 
of regular diffusion which is probably due to thebbundles of un- 
coloredf ibers apparent in the structure. Burlaps, like rough 
papers, will rapidly loose their reflecting powers as they be- 
come coated with dust. 

Turning our attention to the results secured from the 
samples of painted surfaces we see a marked difference in the 
curves, as compared with the other surfaces. The paints were 
carefully prepared on sheet metal so *:hat they presented a very 
smooth surface. Paint gives a very considerable amount of 
surface reflection of white light in spite of the pigmentswith 
which they are colored . This is because of the fine particles 
of color intermingled with the white pigments. Diffusion from 
paint is very regular and from the luster of the surface is very 
strong in comparison with the papers and ather wall coverings. 
The color effects show the same characteristics in paints as 
the other surfaces. 

Samples #130, lcl,and 1Z2 which are very light colors and 
yellow, show a great regular reflection and mtich as a matt surface. 
The darker colors however, for the incident ray normal to the 
surface show by the curves a rapid diminution of regular reflect- 
ion as the incident ray leaves the normal position.

From the foregoing we can now siommarize the qualities 
which effect the reflecting pov^er of the surface into:- 

Pirst, the angle at which the light strikes the surface; 
Second, the nature of the surface( smoothness); 
Third, the color of the materiel; and, 
Fourth, the color of the illuminant. 
In the illumination of rooms the diffused reflection from 
the walls and ceiling is an important item. We can determine 
to what extent such reflection would be of benefit by supposing 
a single light source to illuminate the enclosure. This source 
will give out its light in all directions and every ray will reach 

some point on the surface of the walls from which point it will 
be re-reflected and so on indefinitely until it is entirely ab-- 
sorbed. The increase in illumination prodiiced by this complex : fti 
reflection will equal vinity divided by the quantity, unity minus 
the coefficient of reflection or reflecting power of the walls. 

1 



" Illumination = 



1- C. 
Hence from the preceeding table and this equation we 
can deduce a very close estimate of the coefficient of the re- 
flecting power and the illumination for any given color. Extreme 
accuracy, however, cannot be secured because of the complex sur- 
roundings of the enclosure such as doors, furnishings, and the 
like. Any secondary reflection has approximately the same coef- 
ficient of reflection as the first, so that for two reflections 
of the same beam , the intensity of the beam that finally leaves

the surface is that of the incident beam times the square of the 
coefficient of diffusion; and so on for the higher powers. 

The color and quality of the surface of walls, therefore 
we see plays a very important part in practical illumination, 
for rooms with very dark colored walls requires a very much more 
liberal use of illuminants for en equal intensity than those 
with white or lightly colored walls. The difference, as seen 
from the table preceeding, is great enough to be a considerable 
factor in the economics of illumination in every case where ar- 
tistic considerations are not of prime importance*
